An Irish-Canadian co-production presented by Metro-Goldwyn-Mayer, the sixth and final season of Vikings was developed and produced by TM Productions and Take 5 Productions. Morgan O'Sullivan, Sheila Hockin, Sherry Marsh, Alan Gasmer, James Flynn, John Weber, and Michael Hirst are credited as executive producers. This season was produced by Keith Thompson for the first ten episodes. Bill Goddard and Séamus McInerney act as co-producers.
The production team for this season includes casting directors Frank and Nuala Moiselle, costume designer Susan O'Connor Cave, visual effects supervisor Dominic Remane, stunt action designer Richard Ryan, composer Trevor Morris, production designer Mark Geraghty, editors Aaron Marshall for the first, fourth, eighth and tenth episodes, Tad Seaborn for the second, fifth, seventh and ninth episodes, and Dan Briceno for the third and sixth episodes and cinematographers Peter Robertson for the first to third and seventh to tenth episodes, and Owen McPolin for the fourth to sixth episodes.
According to the series' creator and writer Michael Hirst, the idea to explore Oleg came to him due to the influence Vikings played in Russian history: "I didn't know that Russia is called Russia because it was founded by the Rus Vikings. I learned so much myself and I always do learn when we go different places and explore new cultures and forgotten languages. [...] I was reading books about the Silk Road and about the Rus Vikings and then I read about Prince Oleg, the prophet. He was this extraordinary ruler of Russia and it all kind of fit into place. It seemed the most obvious. It’s also one of the most exciting things to do because we'd been traveling west so much and it seemed logical to go east again. It was an idea that slowly fermented in my mind."
